đ Privacy: Your API key is stored only in your browser's localStorage and never sent anywhere except directly to Anthropic's API for token counting. It's never transmitted to any other server.
âšī¸ Why provide an API key? With an Anthropic API key, Claude models will use exact token counts instead of estimates. This is free (subject to rate limits). OpenAI models use TikToken for accurate counting without an API key.
